Researchers have used artificial intelligence to predict dozens of previously unknown carbon crystal structures, including at least one with a calculated hardness exceeding that of diamond. The ...

Carbon is known for its plentiful allotropes, such as the naturally existing graphite and diamond, as well as synthetic compounds like the "buckyball" fullerene and graphene. Due to its unique valency ...

Molten carbon can form into either diamond or graphite. A new study shows how graphite can sometimes form even under conditions that should lead to diamond. (Getty Images) The graphite found in your ...

Under high pressure, elements on the top of a column usually take on structures similar to elements further down the group. These different forms are known as allotropes. Ozone is an allotrope of ...
